  1. My_Summer_Term_Work Ralf Lindau Diplomanden-Doktoranden-Seminar Bonn, now Cologne – 9. July 2007

  2. Projects & Studies I • Of course teaching ( 0 k€) • Do students need to know about Curvature Terms to understand the Coriolis force? • Geoland (100 k€) • Calculation of global soil moisture fields from AMSR • End of project 31.03.2007 • Final report (financial & scientific) • GRAS-CMSAF-SAF Study ( 25 k€) • Validation of Layered Precipitable Water from Champ (GRAS-SAF) and ATOVS (CM-SAF) by radiosondes • Report delivered, but pending because of suspicious biases in CMSAF retrieval Diplomanden-Doktoranden-Seminar Bonn, now Cologne – 9. July 2007

  3. Projects & Studies II • OMDI III and IV ( 36 k€) • Proposal for a future study (1. Dec 2007 to 30. June 2008) about error covariances of satellite retrievals • Advantages of Iterative Lindau Kriging compared to ordinary Block Kriging • LandCaRe (166 k€) • Stand-alone runs of TERRA on 2.8 km resolution driven by 18-km LM-Consortial runs Diplomanden-Doktoranden-Seminar Bonn, now Cologne – 9. July 2007

  4. Susp.TPW bias of ATOVS - 0.82 mm - 3 % + 7.08 mm + 27 % No NCEP + 3.67 mm + 14 % The bias using GME as first guess (standard) vanishes for „No first guess“ and is doubled, if NCEP is used. GME Diplomanden-Doktoranden-Seminar Bonn, now Cologne – 9. July 2007

  5. Error Covariance D = ((x1 + Dx1) – (x2 + Dx2))2 D = 2 Var – 2 Cov + Err1 + Err2 - 2 ErrCov Diplomanden-Doktoranden-Seminar Bonn, now Cologne – 9. July 2007

  6. Error Covariance D = ((x1 + Dx1) – (x2 + Dx2))2 D = 2 Var – 2 Cov + Err1 + Err2 - 2 ErrCov S = (x1 + Dx1)2 + (x2 + Dx2)2 S = 2 Var + Err1 + Err2 Diplomanden-Doktoranden-Seminar Bonn, now Cologne – 9. July 2007

  7. Error Covariance D = ((x1 + Dx1) – (x2 + Dx2))2 D = 2 Var – 2 Cov + Err1 + Err2 - 2 ErrCov S = (x1 + Dx1)2 + (x2 + Dx2)2 S = 2 Var + Err1 + Err2 S – D = 2 Cov + 2 ErrCov Diplomanden-Doktoranden-Seminar Bonn, now Cologne – 9. July 2007

  8. Negative Kriging weights Kriging is solving this matrix: Kriging error is: Diplomanden-Doktoranden-Seminar Bonn, now Cologne – 9. July 2007

  9. LandCaRe 2020 TERRA stand-alone Resolution 0.025° (2.8 km) 250 x 300 grid points Reality/Computation factor 60 20 years: 4 months Diplomanden-Doktoranden-Seminar Bonn, now Cologne – 9. July 2007

  10. Soil Temperature After 6 days (2.5 hours computing time) the course initial resolution is partly downscaled Diplomanden-Doktoranden-Seminar Bonn, now Cologne – 9. July 2007

  11. Uckermark If the domain is reduced to 1° by 1°, (approx. area of Uckermark and Weisseritz county): Reality/Computation factor: 3000 20 years: 60 h Soil Temp, 1. Nov Land-sea mask Soil Temp, 1. Feb Diplomanden-Doktoranden-Seminar Bonn, now Cologne – 9. July 2007
